SPECIFICATION forming part of Letters Eatent No. 593,112, dated November 2, 1897. Application filed May 14, 1897. Serial N 0. 636,616. (No model.)

10 all whom it may concern:

Be it known that we, JOHN W. MoNAncH. and CHARLES VnRTRnEsn POLLOCK, citizens of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to certain new and useful improvements in that class of horseshoes which are provided with a yielding tread, having for its objects to provide a shoe of this character which is simple and cheap and one which will effectively relieve the joints of a horse frpm the shocks and jars consequent upon itsfeet strikinga hard pavement and prevent slipping upon asmooth or wet and icy pavement or when the horse is brought to a sudden stop.

Vvith these objects in view the invention consists in the novel features of construction and arrangement of the parts hereinafter more particularly referred to.

In the accompanying drawings, forming a part of this specification, and in which like letters and numerals of reference indicate corresponding parts, Figure 1 is a perspective View of the invention. Fig; 2 is a transverse sectional view on the line 00 w of Fig. 1. Fig. 3 is a detail sectional view of one end of the horseshoe, illustrating more particularly the adjustable securing and tightening devices for the yielding tread. Fig. 4 is a detail perspective view of the opposite ends of a modified form of the invention, the intermediate portion of the shoe being broken away. Fig. 5 is a similar view of another modification, and Figs. 6, 7, 8, 9, and 10 are detail and cross-sectional views of modified forms of the tread.

Heretofore in this class of inventions it has been proposed to provide a horseshoe having a solid metal base with a yielding rubber tread which is either vulcanized directly to the base or otherwise secured permanently thereto, but such shoes are objectionable for the reason'that when the tread becomes worn or injured the whole shoe must be removed and thrown away. In addition to this horseshoes provided with yielding treads wear away much'more rapidly than those formed wholly of metal, and when the construction of a shoe of this kind makes it necessary to remove the shoe whenever the tread becomes worn and to replace it with a new shoe the hoof of a horse soon becomes ruined by the numerous holes formed by frequent shoeing. Such shoeing, too, is expensive, and the employment of shoes such as referred to is attended with considerable expense, and they are objectionable on this account. It is the purpose of the present invention to overcome all of these disadvantages, and to this end is provided a shoe having a solid base adapted to be attached directly to a hoof and a yielding tread supported upon the base by means of adjustable securing devices which permit the ready removal of the tread from the base without necessitating the removal of the base itself from the hoof, and which securing devices likewise permit the equally expeditious attachment and tightening of the tread to the base when the base is attached to a hoof. Referring more particularly to the drawings, A designates the shoe, which may be of any required shape and size, comprising a base 1 of suitable metal, having at its inner edge a downwardly-projecting flange 2, the outer face 3 of which is beveled or inclined inwardly and upwardly, forming a channel or recess a. At its opposite ends the base 1 is provided with projecting lugs or bearings 5, one or both of which is preferably provided with a conical opening 5, which extends through the lug from the rear face thereof to its inner face.

Within the channel 4:, bearing upon the base 1 and the outer face of the flange 2 and projecting beyond the edge of said flange, is a yielding tread B, formed of any suitable material-such as rubber, fiber, 850., or of a combination of such materials with metal or canvas-and this tread may be of any desired thickness and of any desired contour in crosssection. Connected to this tread are suitable means for securing it within the channel 4. As shown in Figs. 1 to 3, this means consists of a non-extensible flexible metallic rod or wire 6, extending longitudinally through the tread near its base and having its ends screwthreaded and projecting beyond the ends of the tread. These threaded ends are adapted as indicated, and adapting the securing-nuts 1 to extend practically through them it will be seen that the threaded ends of the rod 6 may be comparatively short, as it is only necessary to extend them a short distance into the openings 5 in order to be engaged by the nuts. It will be noted, too, that the securing-nuts may thus be afforded an extensive threaded bearing-surface upon the ends of the rod 6 and that the nut, by being practically wholly countersunk in the lug 5, is protected against injury or from accidental loosening by com- 1 ing into contact with a stone or other hard end of the rod is inserted laterally into the object.

Upon tightening the securing-nuts 7 upon 2 the ends of the rod 6 the tread is drawn into the channel 4: to closely conform to the outer face of flange 2, and during such tightening, by virtue of the inclination of such face, the

tendency of the rod 6 is to force the tread upwardly into the channel and into firm contact with the base 1, thereby providing a solid bearing not only for the inner face of strip 20, provided at its the tread, but for its base also.

It very often happens in use that the tread is stretched or worn, causing it to become 1 loose upon the solid portion of the shoe, and T when this occurs the loosen ess may be readily taken up by tightening the securing-nuts 7,

thereby drawing the tread into closer contact 1 with the base and flange of the shoe.

In practice while it is preferable to vulcanize the flexible securing-rod within the yielding tread it may be detachable therefrom to 1 permit its use with a new tread, making it 1 only necessary to throw away the worn-out body of the shoe from a hoof, thereby saving tread.

As hereinbefore stated, the yielding tread B may be formed of a combination of flexible 1 rubber or fiber and metal, and in Fig. 6 is illustrated one form of tread constructed in this manner which consists of a series of yielding sections 10, between the adjacent ends of which are interposed metallic leather or wood washers 12, which may or may not be vulcanized to the yielding sections and may be of the same diameter and contour as the tread to lie flush with the outer surface 2 thereof, or of less diameter than the tread to permit greater yielding, but prevent undue wear.

vided with projecting points 12, which exice or snow.

In Fig. 8 the tread is provided with longi tudinal strips of wire-gauze 13, which are embedded and vulcanized in it, and in Fig. 9 the tread is vulcanized to a nonextensible canvas strip 14 and is provided with a series of embedded wires 15, vulcanized within the same.

Instead of the parallel wires shown in Fig. 9 a coil of spring-wire 15 may be embedded or vulcanized within the tread to extend longitudinally through it, as shown in Fig. 10, which spring, in addition to serving to prevent tearing or wear of the yielding tread,

also serves to maintain its shape.

In the modified form of the invention illustrated in Fig. at one end of the rod 6 is secured in the manner hereinbefore described, but at its opposite end the rod is provided with a head 16, adapted to [it into an enlargement 17 of an opening 18 through the lug 5. Intersecting this opening 18 is a slot '19, extending to the side of the lug, through which the opening 18. After this the head 16 is drawn into the enlargement 17 by the nut at the opposite end of the rod, and the lateral disengagement of the rod with the opening 18 is thereby prevented.

In the modified form of the invention shown in Fig. 5 the rod 6 is dispensed with and the tread B is vulcanized or otherwise permanently connected to a thin flexible metallic ends with thickened turned-up portions 21, having threaded projections 22, which receive securing-nuts 23. These nuts instead of being conical are formed with internally-threaded nipples 24, which extend wholly through and turn freely in openings in the lugs 5.

From the above it will be apparent that a horseshoe having a yielding tread is provided which is not only simple and effective, but one in which a worn tread may be quickly and easily replaced by a new one by an unskilled person without removing the main the expense of shoeing and making it only necessary to throw away the worn tread of the shoe without the securing devices.
